1 is a schematic diagram of a camera assembly in accordance with an embodiment of the present invention. Referring to FIG. 1 , in the embodiment, the camera assembly 100 includes a mounting bracket 110 , a camera module 120 , and a cushioning material 130 . The holder 110 has a receiving groove 112. The camera module 120 is disposed in the accommodating groove 112 , and has a gap g between the camera module 120 and the sidewall 112 a of the accommodating groove 112 . The cushioning material 130 is filled in the gap g to position the camera module 120 in the receiving groove 112 of the fixing frame 110. Thus, by filling the gap g with the cushioning material 130, the camera assembly 100 can be slowed down or the electronic device 50 (shown in FIG. 4) of the subsequent application camera assembly 100 can be caused by falling, collision or other external force. The optical axis of the lens of group 120 is offset.

Specifically, in the present embodiment, the Young's modulus of the cushioning material 130 is lower than the Young's modulus of the holder 110. In other words, the material of the holder 110 can be selected from materials having a large Young's modulus. The material of the fixing frame 110 is, for example, metal, ceramic or plastic, wherein the metal material may be stainless steel, aluminum alloy, aluminum alloy or copper alloy. Alloy), zirconium alloy (Zr alloy), titanium alloy (Ti alloy), zinc alloy (zinc) Alloy, Zn alloy), magnesium alloy (Mg alloy) or lithium alloy (Li alloy). The ceramic material may be aluminum oxide, aluminum nitride, silicon oxide, silicon nitride, zirconium oxide, boron nitride or carbonization. Silicon carbide. In more detail, since the Young's modulus of the mount 110 is high, the mount 110 is less likely to be deformed. The cushioning material 130 has elasticity and flexibility and can absorb impact energy, such as resin, silicon rubber, polyamide (PA), polyurethane (PU), polypropylene (polypropylene). PP) or rubber (rubber). Thus, the cushioning material 130 has functions such as shock absorption and shock absorption, and can mitigate the impact. Even if the camera assembly 100 or the electronic device 50 (shown in FIG. 4) is affected by dropping, collision, or other external force, the optical axis of the lens of the camera module 120 may be shifted. The present invention does not limit the material of the holder 110 and the cushioning material 130, and it is possible to select a suitable material according to requirements.

Since the high Young's coefficient fixing frame 110 is combined with the low Young's modulus buffer material 130, the fixing frame 110 can protect the integrity of the camera module 120 while the camera assembly 100 is dropped, collided, or subjected to other external forces. The material 130 can slow down the shift of the optical axis of the lens of the camera module 120. Preferably, the camera module 120 has a distance between all the sidewalls 112a of the accommodating slot 112 (for example, the four sidewalls 112a of the accommodating slot 112 in FIG. 1), that is, the camera module 120 of the embodiment. The side wall 112a of the accommodating groove 112 is not contacted. As such, after the buffer material 130 is filled in the gap g, the camera module 120 can be slowed down, collided, or subjected to other external forces. The effect is that the optical axis of the lens of the camera module 120 is shifted. In this embodiment, the minimum distance d between the camera module 120 and the inner surface of the side wall 112a of the accommodating groove 112 may be 0.8 millimeters (mm), but the invention is not limited thereto, and may be based on Demand adjustment.

Referring to FIG. 3, in the embodiment, the camera assembly 100b has two camera modules 120a and 120b similarly to the camera assembly 100a described above, the main difference being that the camera assembly 100b The number of the mounts 110 is two. Specifically, in the embodiment, the camera assembly 100b includes two mounting brackets 110, and each of the mounting brackets 110 has a receiving slot 112. The two camera modules 120a and 120b are respectively disposed in the receiving slots 112 of the corresponding mounting brackets 110, and each of the camera modules 120a and 120b and the side wall 112a of the corresponding receiving slot 112 have a gap g therebetween. The cushioning material 130 is filled in the gap g. The material characteristics of the fixing frame 110 and the cushioning material 130 and the position between each of the fixing frames 110 and the corresponding camera modules 120a and 120b can be referred to the foregoing description, and will not be further described herein. As such, after the buffer material 130 is filled in the gap g, the optical axis of the lens of the camera modules 120a and 120b may be shifted due to dropping or other reasons. Similarly, the two camera modules 120a and 120b of the present embodiment are preferably bilaterally symmetric with the same axis A as a center line. Furthermore, the two camera modules 120a and 120b of the present embodiment have different pixels. Thus, when the camera assembly 100b is applied to the electronic device 50 (shown in FIG. 4), the camera assembly 100b can capture more image data by using the two camera modules 120a and 120b having different pixels to facilitate subsequent operation. Image processing and diverse applications. For example, the auxiliary camera module (eg, camera module 120a) assists the focus speed of the primary camera module (eg, camera module 120b). For example, the image data may be the distance between each object in the image and the camera modules 120a and 120b. Accordingly, the camera assembly 100b of the present embodiment has a variety of applications.
